Abstract:
In mining operations, a number of mining machines will have flexible cable attached thereto which then drag along behind the machine as it operates. When the machine moves in a backward direction, the machine often times will run over and damage the cable. In the past, the cable has been moved manually to prevent damage. The disclosed invention provides an automatic device which will lift a predetermined length of cable above the groun so that the cable will not be cut as the machine moves backward a given distance.
